Abstract

A method for fabricating muntin grid pieces includes steps that attach an outer muntin grid element to an inner muntin grid element to form a two piece muntin grid piece. The outer muntin grid element surrounds at least three sides of the inner muntin grid element and may be held to the outer muntin grid element without connectors such as adhesive. The outer muntin grid element may be a slit tube that is spread open to be positioned over the inner muntin grid element.
